OC48 line modules pair with OC48 FRAME I/O modules to deliver unchannelized OC48/STM16 POS operation through one line interface.
The OC48 I/O module supports single-mode (intermediate reach or long haul) operation through an SC full duplex connector.
The interface stack for the OC48/STM16 interfaces is the same as that for OCx/STMx POS interfaces (Figure 6).
The OC48 line module can be installed in the router’s turbo slots, numbered 2 and 4. When the OC48 line module is installed in a turbo slot, it spans slots 2–3 and 4–5. The bandwidth of slot 3 or slot 5 is used for a line module in slot 2 or slot 4 if that line module requires the turbo slot.

Note: If a line module is installed in slot 3 or slot 5, and the line module in slot 2 or 4 requires bandwidth, the system configures the line module it detects first. The state of the other line module is displayed in the show version command output as disabled (cfg error). |
